Current: charge over times
*Charge is measured in coulombs
Time for this is seconds

How is current and resistance inversely related?

When resistance goes up
Current goes down

Current~ 1
------
Resistance

What are the symbol for Current and Voltage, Resistance?

Current = I
Voltage = V
Resistance= R

How is current and voltage directly related?

As voltage goes UP
Current goes DOWN

current~voltage

What is ohm's law?

I = V
-
R

Current = voltage
-----
resistance

1 ampere = 1volt
--------
1 ohm

Voltage= current * resistance

What is the formula for ampere?

ampere = volt
---=
ohm

What is the formula for current?

Current= voltage
--------
resistance
I = v
-
r

how is voltANG and resistance DIRECTLY RELATED?

AS VOLTAGE goes up RESISTANCE goes UP

What is an other formula to find voltage?

joule
-----
coulomb

What does force consist of?

potential difference
electric pressure
pressure difference

What does 1 Ampere equal?

1 Amperes = 1COULOMB
---------
seconds

Symbol is A

What does force consist of?

potential difference
electric pressure
pressure difference

1 watt = 1 v * AMPERE =electric power

energy over time = powers

watts is a unit of POWER

watts is a unit of POWER

dc & ac

A Direct Current (DC) referring charge flowing in one direction. A battery produces direct current in a circuit because terminals of the battery always have the same sign of charge.

Alternating Current (AC) electrons in the circuit move first in one direction then in the opposite direction, alternating back and forth rather than in fixed positions. This action is accomplished by alternating the polarity of voltage at the generator or other voltage source.

watt / kilowatt

Power is a watt, and kilowatt. Energy is kilowatt-hour. Power: watt, kilowatt; energy: kilowatt-hour.
